Figure 2. Effect of EO on cell viability. When treated with 25 mg/mL EO, AMD cybrid cells showed consistently increased viable cell numbers at 24 h (A), 48 h (B), and 72 h (C) compared to their untreated counterparts. ** indicates p<0.01. Data are presented as mean ± SEM and normalized to untreated AMD cybrids which were assigned a value of 1.
